Kind of fortuitous that I randomly check PSW today - one of the partners of Squeek Lights here, and we do love our Chauvet. I'm more the operations guy, Victor is the one out on the road, but we also send out a lot of tours with a TM or stage tech running the lights. I've got plenty of experience doing shows with Rogues though, both with Squeek and with other and previous employers.
The R1 Spots are about equal to a Studio Spot 575 with a new lamp. The R2 Spots are about equal to a MAC700 with a new lamp. In both cases, part of this is due to the higher color temp of the Rogues, but that seems to be desirable in concert & event fixtures right now. In color, the R2 is brighter than the 700 because it uses color chips instead of color mixing and doesn't zoom so there are fewer optical elements in the way of things. I did multiple shootouts at a previous employer with the Rogues against their rental fixtures.
I would solidly recommend R1 Spots if you're looking for something to double the punch of 250 fixtures. The gobo selection in the R1 Spot is superior to the R2 Spot IMO, but if you need the color selection of the R2 it's a great fixture as well. The iris is also a really nice addition on the R2, I've used it to get "poor man's beam" looks plenty of times, and it looks really good if you can black out everything else, drop the iris down to about 25% open, and drop in the frost. Keep it in a bright color like white, yellow, or light blue and it's a killer look.
Something else to consider if you're not doing big rooms is the Chauvet DJ Intimidator Hybrid 140 SR or the Intimidator Spot 375Z. These would both be great in up to 800 cap rooms or more. In particular if you're looking at R1 beams I'd take a look at the Intimidator Hybrid 140 SR, killer fixture with a 6000 hour lamp life. I'm told it's made in the same factory as the Rogues, so better build quality than the old Intimidators, and it's got an omega bracket instead of that pesky allen key bolt bracket. I saw these at LDI and was impressed. If you're thinking that they won't be bright enough, remember that the Rogue RH-1s with a 280 watt lamp are used in stadium shows. The Intimidator Hybrid 140 SR is basically a baby RH-1. You could fit a 4-pack of these units in a 1/4 x 1/3 pack case.
Disclaimers - partner in Squeek Lights and dealer for Chauvet. I've been a fan of Chauvet Pro for years though, just ask any of my previous employers...
