Kalmyi:
Any help is appreciated, thanks for reading!
At L45 I would focus on unlocking more levels (ie earning more XP) so that you have more options to choose.
Clubs you can choose from now you will simply look to upgrade shortly and everything you have now will suffice.
I chose to use starter clubs and coin rental sets as I worked towards unlocking better clubs and avoid buying and replacing lower end clubs quickly.
I set my sights on --L51 3wd, L55 Driver and L59 irons... I picked up some bargain wedges along the way... But those where the clubs I felt would last me awhile and would be playable up to the Legend tee and possible longer if I had not unlocked better clubs by that time.
