Damo I'm 6'1 and 105kg so not exactly a midget.
You are right the seat moves you up and forward, however it gave a much more aggressive riding position I found, I don't do any long distance stuff, just hill blasts. The LD seat gave me a lot more control over the bike.
I don't think you can go wrong with any of the Aftermarket seat companies with the high back. They all seem good.
