Thanks people for the replies
As I suspected regarding the powerThe protool is the most powerfull cordless around. Since I'm used to my current Dewalt 18v XRP dill the weight is not a problem at all.
I think it would be better for me to order the Protool 18v i.s.o the T15+3 since my works demand lots of times powerfull drilling in thick hardwoods and since I'm already addicted to cordless drills I don't see myself very often using corded drills if not when I need to make a lot of drilling in concrete walls and floors.
Since I live in Curacao I can enjoy the tools from all over the world without worrying about the electricity as we have both 120 and 240v standard in each home.
