[b]Don't you think the protein is interfering with the absorption of the aminos 30 minutes later?

This is quite a subjective answer on my part, but I 'feel' when my stomach empties (at least I feel 'something' that I interpret as that). Mine does take around 40-80 minutes (around 40 for a shake, & anything up to 80 for a meal that contains some fat - obviously a crazy gut-buster meal can take longer), so if I'm having a shake I have that around the 80 minute pre-training, once I feel it's moved on I take my amino acids & wait around 20-30 minutes. I seem to have fairly quick transit times (again supposition, I'm going by feel), someone else may need as long as 2 hours or so pre-training for their meal to move on & be ready for amino acid.
Another option I've seen touted that might be useful is to have the pre-workout protein, then add your amino acid to your workout drink, as long as you don't go crazy about the amounts used & you've not got a sensitive gut you should be ok as amino acids need not digestion, simply assimilation.

No problem for me boys re protein shake in fact a few times its been 30mins before training but then again I am not mortal lol

I've been taking Superpump 250, and Jack3d. I want to try something new. Any ideas on what the next best things are?

I wouldn't choose either Superpump 250 or Jack3d. I'll explain why:
First off Superpump 250 contains Salicin, & that is an NSAID (Non-steroidal anti-inflammatory drug), it is a close relative to aspirin. NSAIDs are thought to inhibit muscle growth, so I couldn't recommend them.
Jack3d is an NO2, NO2 just gives you brief pump, there's no research to say it does anything else.

Basically you are taking 2 products with arginine & creatine in. & one or the other has beta alanine & caffeine in there. Most of the rest is 'fluff'.
You'd probably save money by going to a bulk buying company & getting a creatine, if you want an arginine type effect I'd actually go for Citrulline Malate as it appears to increase arginine levels in the body to a higher level than taking a similar amount of arginine [ NOTE: do not take any arginine, or arginine forming product without taking l-lysine]. Also any arginine, or arginine forming product can make cold sores worse, be cautious if you suffer from them, so you need a L-lysine product if you want to take a arginine or arginine forming product, get that if you want to take it. Some beta alanine (this product is not proven yet, but has some interesting results in studies) & some caffeine (if you need the buzz to get 'up' for a workout).
So assuming you wanted the 'main stuff' in the 2 products you mentioned I'd nip online to a supplement bulk buying place & buy:

Creatine
Beta alanine
Citrulline Malate
L-lysine
Caffeine

Products I would consider:

Protein powder have it both pre-workout & post - you'll get more benefit having pre & post workout protein than any other supplement.
Also if you want to add mass I'd consider eating more. Plan to progressively eat, go from where you are right now & add 200 cal to your daily intake & stick at that for a few weeks. Stay at that until you are used to it, then go up another 200cal, once you start reaching the point you are eating 800-1,000cal more than you were & you stick at heavy training the gains will start to come.
Not sexy like the latest 'Ultra muscle' supplement, but more effective-just spend the cash you would have wasted on the latest gimmick supplement & spend it on food. Add in enough rest, trying to stay stress-free & hard training & you'll blow up like a monster!
