Tail end tinkering

Popped down to T-city to talk rear muddy lopping and sissy-bar angles. Most US bobbers have very short rear ends and I can only presume that's cuz they don't get the rain we get here. 
I'm no big fan of soaking wet sprays of rainwater and road crud up my back so have opted for a less extreme bob. 
Some of the look - but hopefully none of the water cannon effect.
Also talked sissy-bar height & angle. One of the probs of a softail, rather than hardtail, is that its far harder to get the angle onto the frame right. 
In addition, fitting the rear muddy as an integral part of the rear swing-arm leaves a yawning gap between the seat area & the fender which can never replicate the flowing line seen on a hardtail when the frame line runs straight down from steering head to rear axle and the seat can sit tight back against the rear mudguard.
In this case, I know I'm gonna have a gap - just need to ensure the eye isn't drawn to it.
The sissybar angle is part of that. Too upright or too laid back and it will jar. 
And because this is a softie and the bar's hard welded to the moving swing arm, it can't be too high or smacks in the back of the head may be the new reminder every time I've ridden over a speed hump.
