Don't always think bigger is better or faster, it's not. At the last Berwyn Bash a .18 beat everything there including a collari.30.....

if you want BIG and FAST go with a NovaRossi 528... the 3 port can be had around $220 and the 8 port for around $320. I would go with the bumpstart version (as they have a pullstart version also but the pullstarts kinda suck and break all the time)
