I don't feel Peer pressure at all (though it would be nice to swap lenses occasionally) All the togs i've met that i respect actually have tried my kit and liked it. most are either canon or nikon (or both in a couple of cases) shooters but they need the rental support since they have no need to own some of the insane lenses but do need them for shoots occasionally (where the cost of rental is built in to the bid)
OTOH there are a lot of mostly canon (rarely Nikon for some reason) newbies who will slag my gear at events . I'll likely be standing beside them using a fast 50 and a K7. with my k10 loaded with another lens. If it's at a big outdoor function i pray for rain, i'll swap to a WR lens and watch them run for cover while i keep shooting. When I look over at what they are shooting 80% of the time it's some rebel variant with a kit lens. If they have the big FF option and the white lens and still have this attitude i will notice it's on green mode
Point is the Canikon guys who know photography will never slag off your kit and will likely ask to see it and discuss the advantages if you talk gear at all. mostly with these guys i would talk technique or about what we managed to capture. Only 2 things would get me over to Nikon - FF if i finally decided i had to have it barring all else, and rental ability. Nothing would get me to Canon, nice enough gear, some Very good (expensive) lens but i can't stand the ergonomics
One option for this one event would also to rent a body only at the local rental. generally it's not expensive to rent a body for a day, and the weekend rate is usually the same as the single weekday rate
Personally i have almost no desire to shoot a bazooka like that but i rarely shoot wildlife
