If you think five or six pumps constitutes a workout then you must be in a poor state physically. As for heavy springers, i bought a HW 80 when Hull first imported them. That was a mistake of collosal proportions, weighed i think 8lb 10oz without a scope. It wasn't as accurate as the Ace and was a real bind to cart around, i soon got rid and stuck with the Ace which incidentally i still have.
