I have no problem in switching between my 177 S200 & Sirocco .20 at the club ive had the Sirocco for about 18 months and i've had no problems with leaks and its still shooting at 11.6 ft/lbs with H + N ftt's ... i used to have a HW90k but found it a very heavy gun to lug around a shoot all day ... i have toyed with the idea of a Venom tuned springer though
