Ha - it is a disease
I am not surprised you regret selling that P10 - it is lovely bit of kit.
I was lucky enough to find another one after buying yours some time earlier last year and "had to have it" coz they don't come up that often and when they decide to leak - having another one in reserve means I don't have to rush down to Aldi to see if they have got an offer on their box of "O" rings
George is having a go with a P10 to shoot his MPL series with this season - so we could have another P10 convert joining the clan - most people that shoot the P10 like the easy cocking action and the way they shoot.
The rest of your list looks impressive - if you get that lot past the wife you will be dong very well
