I too can recommend MJM in Goulburn.
I loved the seat on my Wee but truly hated the V2 seat, MJM was great to deal with and the results were perfect.
He has spare seats so you can stay on the road while weaves his magic.
Many people find the distance between the seat and the pegs on a Strom is short, going to a low seat makes that even worse so you may want to consider a peg lowering kit too.
Some find just taking the rubber bumpers off the stock seat pan gives them what they need, have you tried that ?
I dropped the front of my Wee 10mm to speed up the steering and there was the added benefit of being able to get a firm grip on the ground (until I put the 1" lift under the back)

He with the most toys wins.
Out of my depth in a puddle.
Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
