I've always been an advocate of PWG "going out of the box" to find new regular talent - it's what netted them El Generico and Kevin Steen, and I really enjoyed the inclusion of guys like Jimmy Jacobs, Tyler Black and of course PAC for All Star Weekend 4.
One wrestler who is arguably one of the top 5 talents in indy wrestling, and has the advantage of not being caught up in the FIP/ROH/TNA triad of Priority Booking, is Mike Quackenbush. I've introduced a lot of wrestling fans whose knowledge of the indy scene doesn't go beyond ROH, TNA and PWG to Quack, and they've all been instantly blown away by what he's capable of doing. His matches with Claudio at Best of the Best 5, TPI '06 and CHIKARA's Negative Balance are regarded as incredibly matches, and rightfully so. I've never really seen anyone perform incredibly complex lucha so effortlessly as Quackenbush, and also keep up with the European matwork of guys like Hero and Alex Shelley. Quackenbush is one of the few guys I have NEVER seen have a bad match...and the tremendous respect he receives in places like IWA-MS and CZW are proof he's an asset to any company he competes in.
I'm aware he was previously booked in PWG at Use Your Illusion 4 as part of a CHIKARA touring indy 6-man tag and didn't make much of an impression - but that was 2 years ago when the CHIKARA students weren't nearly as advanced as they are now.
Quack coming can bring about a lot of potential "dream matches" that wouldn't happen elsewhere - Quack/Quicksilver, Quack/Generico, Quack/Scorpio Sky would all be tremendously entertaining additions to any PWG card.
A Quack/Shelley, Claudio, or Hero match would be a great introduction to him for PWG audiences, and I think he'd make a great impression on PWG fans. After all, why should IPW and IWA Deep South get to hog him?
