Hey gang, hows the snow flying season?

Question; I built a Sig Senior that I've recently had to strip the bottom sheeting off of the fuse (glow fuel soaked[:@]). When I built it I did some er... re-engineering for strength in a "few" places and wound up with a rather portly senior. I've got 4 landing gear blocks in it, the original trike one, the conventional gear, and two for floats. I could go either way on replacing these mounting blocks. I could probably sand on them enough to get rid of any glow soak or just replace them. How beefy do mounts need to be for floats? These are hardwood landing gear blocks from sig/etc. Can I use something smaller/lighter for the floats?

Thanks
