Changing the swingweight of Driver/FW/Hybrids

[turkish]

Just wondering what is likely to change by changing swingweight up and down in these clubs?

My driver, FW and Hybrid are 915 but only ever see the red 9g standard weights but have seen you can buy different weights on ebay so just wondering what's likely to happen when you change these?

Just wondering what is likely to change by changing swingweight up and down in these clubs?

so largely the option of the differing weights are really to do with swingweight and 'feel' - as opposed to affect 'ball flight' just by weight difference

think the weights kits from titleist for the 915 is - 4g(white) - 7g (green) - 9g (red) - 11g (blue) - 14g (black)
so as mentioned changing weight will alter swingweight (could be useful it changing shaft length to help get someways back to original swingweight)

as the single weight position is low and back it could very marginally affect spin rate but by very little would guess - so not so much that there would be any great difference in the shot outcome - the impact strike location has more influence first off anyways - as different impact strike locations, toe/heel will more affect spin rates/flight traj/curvature anyways as it always does

only real ways to know would be to order a weight kit and try it out as regards how it might help/hinder delivery of a centered strike in line with the cg(sweetspot)- but would need to try it out on a launch monitor (if Gc2 Hmt or dual radar trackman 4 they give ball strike location on face - with any other LM it would need some foot spray or impact tape)

if fitted for the clubs first off shouldn't really be any need to mess with a weight change - but really too for most folks if bought off the shelf still should be no real need to change weight as the red standard weight is the one designed to match the head & shaft length to around the optimum swingweight for the club
