Wow, Melee much Marm?
I do like WP though, have a Dual Blades/WP scrapper that indeed was very solid. With plenty of IO my War Mace/Shield brute was too.
Once you get a character to 20, I'd also recommend trying out a Widow. I've not played a Claws/SR, but I'd imagine my Night Widow would be somewhat similar.
Really though, I'd just say make as many combos as you feel like trying or have ideas for. Your favorites will shake out.
