Hey Brian, you should do a search on here under remotes, 'cause they just had another thread about this. Anyhow, as long as you get a quality one that won't break on ya', the only drawback is getting hung up on everything. Oh, and setting your gun down on a table, then walking off and pulling your gun off onto the ground.
It does make your gun lighter, obviously, and if you're running CO2, then it acts as an expansion chamber. I used to have that set-up back in the day, back when they were in style. I've still got my monster steel-braided remote somewhere, that dang thing almost put me on my rear more than a couple times, it grabbed every branch on the field.
