Cutting down shafts / effecting swing weight

Ordered a different weight off ebay (9g) paid £9.99 instead of £6.99 that I paid for the 8g weight however didnt realise the other was from a hong kong seller.. plus will take few days longer to arrive lol would rather pay the more and get the 9g .. slightly better gramage aswell

takes the formula to 7.5 re added to a club that will have lost 7.5 with cutting down

well approx.. may add 6.5 but worth doing to keep the m2 at its best whilst cutting down

im nights this week so perfect time to play about.. once the grips arrived ill get the clubs cut down

weight can be added in the week
