Ok, Basic question- how much difference would I see between a bullet 2.5 and a 3.0 pansh [does it really matter what model?! They are all described the same!} I have always had good size differences between my kites and do not know how small or large of a difference I would see with a small 1/2 meter size difference. Does anyone have a 2.5 and 3 of any type that can give some info? Thanks

It is the shape of the kites that is different ( also to a degree angle of attack ) The Bullet has a lower aspect ratio ( wider ) so will create more downwind pull and less lift . The Blaze or link have higher aspect ( narrow ) and will each fly that much faster = produce more lift.
This is sort of a guess but I expect a 2.5 fast kite would create more apparent power with it's speed and you could work it. The 3.5 Bullet would deliver more raw power in the same wind.

I have never flown a 2.5 but find anything 2 and under usually buzzes around and at 3 they start to act more behaved.

Looks like I got kites mixed up but you hopefully you get the concept on how each would fly + produce power differently.

Thanks for the info- I am still trying to find "the perfect kite'!!
