I'm currently running a windsplitter 12 on my 13 shark. Looking to get a taller windshield to pop on just for long rides to help with wind management. What height should I go with to get optimum wind management? I'm 5'11" with 32 inseam running a stock seat. I've got my eye on 2 different shields right now, the 15in Freedom shield and 15in LRS mako. I can get them for 90-100 bucks .
