Need help on a Cyber-Mage, Want some extra IPs, but which way to do it? Options

[paws2sky]

For some reason, I'm kind of obsessed with augmenting magician. I'll blame ye olde Burned-Out Mage and leave it at that.

Anyway, I'm almost done with a new augmented magician (for SRM New York), but I can't decide how to go about getting his extra IPs. This is pretty much the last thing I need to do for him, BTW.

Currently, I have 16 BP budgeted for a Synaptic Booster (1), but last night I started second guessing that.

I realized I have a couple other options that are actually pretty tempting:

• Sustaining Focus (3) with Increase Reflexes. Saves on Essence, but doesn't get me back a magic point as I have some other 'ware. Major downside here seems to be having to re-cast the spell regularly. On the up-side (and this is a BIG one), I could potentially get TWO extra IPs instead of one.
• Move-By-Wire (1) [Alpha] will cost be about the same number of BP once I juggle my other 'ware around. I'd be able to ditch my Skillwires (3), but I'd have to downgrade my Cybereyes and (pprobably) ditch my Sleep Regulator so I didn't go over .
• Or I could say screw it all and go with Wired Reflexes (1) or (2) [Alphaware]. I'd use the extra BPs to buy up my Magic to 6 (before reductions). Again, I'd have to ditch a bunch of 'ware to do this.

In any case, I don't want my modified Magic Attribute to drop below 3.

Please compare, contrast, and critique each option.

Thanks,
