Replying to Moment Meridian Sizing

I'm set on snagging a pair of the Meridians as a daily driver but I'm on the fence between the 181 and the 187. I'm 6', 175/type 3 skier. 187 doesn't seem that much bigger than my 185 JJ's but despite being full rocker the Meridian seems to have a pretty long effective edge. I think the 181 Meridian has more edge than my 185 JJ's but I'm worried that at 6 feet I'll get tip dive. Anyone on the Meridians able to offer any advice?
