I am just getting round to selecting the prop for my 360.  Could someone advise me what the realistic maximum diameter is to avoid trimming the tips every time you hit a bump on the taxiway, or brake hard?  I have heard various figures from 68 to 72 inches, and would like to know what other people's experience is.  I am looking at a 71 inch prop as one candidate.

Also, can you increase ground clearance by putting a small spacer between the nose oleo and the nose gear fork, or does that introduce other problems?  Thanks.
