IMHO the spider L35 is a little gem for the price. It will see you all the way through to L70+ when you will be more familiar with your style (see forum threads on the topic).
Also consider three evenly spaced wedges when you get to pro. Personally I don't think you can go wrong with the great value L40 something Ping ones. They will see you all the way through to the high level one's when you are Legend.
Iron wise nothing until L59 G20s which will see you easily through to the L79 Bladez.
Levels are not difficult to get through for a good while for you provided you do you daily play to get XP. One hole via Community link will do it for those busy days.
What I would do if doing it again. Can spend more in the pro shop, but that's your choice:)..........Back to the putter sorry I never used the Manta, but thought the rest might be of use:)
