i ride pistols and rocket rockets everyday, and i dont think pistols would hold up to long riding the park every day, i say, buying both would be the best option. BUT i understand thats prolly not an option, i say pocket rockets over the pistols, and also i know i didnt even answer your question about the tech changing, but the ones i use in the park are the ones with the ugly graphics, like the green rocket man or whatever. they work just fine for me in the park.
ive got another version of the pole dangle, its pretty funny too, gets cold when i do it on the lift tho.
