It certainly sounds impressive.

Kind regards,

No cocking increase, or strain increase as the single mainspring has about the same strength of compression as the 2 stock springs, indeed perhaps very slightly less. However, all that power is released much more smoothly and with much improved efficiency meaning velocity does increase.
The 50fps to 100fps (gun dependant) did required 3 clicks down on the 53 elevation but did not run out of adjustment on either gun.
The gun seems to go off with a sharp fast thock, without the boing and twang when using 2 mainsprings
