I am about your ht, so I will throw in my 2 cents. If you have the stock windshield your hands are gonna get wet, if you have a wider aftermarket like I do your hands stay pretty dry. Bobs idea on gloves is very good. If you are moving along at say 50mph and above you really dont get too wet on a RSV, usually just from my knees down. If you are in alot of stop and go you are gonna get wet. I tried cutting my shield down, its easy to do but I got so much buffeting it didnt stay on for more then 2 miles. I have the tallest widest Clearview and I keep it polished with Honda Polish at 60mph it stays pretty clear with rain beading up. Everyone I talk to says the Vmax rear is the best bang for the buck in performance upgrades, but there are lots of others.
As always good tires properly inflated on wet or dry roads.
Good Luck, Craig
