We have the exact model you are contemplating - 335RLBS - please be assured that this is NOT a small space and we have nothing but good things to say about it. As the Nike ads said . . . . just do it! We do not regret going with a TT instead of a 5'er - there are pro's and con's to both routes and IMHO neither have the edge over the other (that may create some comments from others but we all have opinions and as the boss remarks I am somewhat opiniated!)
Good luck with your decision.
