FSA SL-K Crank

I've played around with different combos of cranks and cassettes for some time now. I've been using a 10 speed 11/36 cassette with my 52/39/28 SL-K crank for the past few months on my Catrike "Black". It's a good compromise between the need for climbing gears and the need for speed. The chain gets a little sloppy when going small/small (11t cog and 28t chainring) but there's no need to go there. 
The 28t after market chainring replaced the SL-K 30t chainring. The Driveline Lightest chain guard is a lighten down version of the FSA chain guards Catrike supplies with their trikes. I use it primarily to avoid the usual "you're going to cut someone with that chainring sticking out like that" comments.
