LiPo - 4s2p or is 4s 10000mah suffice?

[10kman]

Looking at LiPos, had my eye originally on a 4s2p 8000mah pack, but saw that there are 10000mah packs, but are not parallel, just series cells, so just 4s in this case.

Specs on the 4s2p are higher -
20C Constant(160 amps)
30C Sustained(240 amps)
50C Burst(400 amps)

Specs on the 4s 10000mah pack -
15C Constant(150 amps)
20C Sustained(200 amps)
30C Burst(300 amps)

The 10000mah pack is heavier and a smidge bigger, but neither of those are a real hinderance to me. Price of the 4s2p is higher, but the outputs of both of them are probably more than enough for my needs.

MGT - Neu 1515 1/y, Monster Pro 125...... The Quark is capable of 300 amps for a burst, so is there really a need for me to have a 2p pack that can put out more than I can theoretically handle anyway? Plus more runtime with the 10000mah pack, 25% more......
