Diff vs. spool for TC4 in VTA???

I've considered making a slipper spool for my VTA TC4 to see if it improves my lap times. Currently I'm running a front diff and I really like the way it allows me to drive hard into corners. However, I feel that I'm losing a bit of acceleration coming out of the corner.

Right now I feel that I'm making a bit of a compromise. Since the diff allows me to drive a little more aggresively into a corner, I feel like I can keep the pressure on the car/driver in front of me and force them into a mistake. However if I cut the corner too tight, the front diffs out a bit and I watch a car with a spool pull away. This negates the advantage I gained going into the corner.

Regardless of which way I end up going, I'm having more fun in VTA this season as I feel all the cars have become more equal in speed with current rules. I am enjoying the actual racing on the track. I have even had to consider strategy of whether to pass for position, or stay behind and pressure the car in front into a mistake. Rarely can I say I raced an r/c car hard AND had fun. VTA is that class for me.

I don't think that putting a one way in your car will hurt you at all. The only time I have noticed that a one way is a problem is if I need to use the breaks. As long as you don't have drag break dialed in, the one way should not effect you entrance speed at all and the benefits of having it when exiting is worth it.
