Front End Configuration

Riding a 2014 P2 in a 51 thats more or less stock right now. I got a retul fit done recently which basically told me don’t bother going much lower (back angle was 17 degrees from level; if that is relevant).

I use a 70mm -7 degree stem with 3cm of headset spacers and PD T2 wing bars with T4+ clip ons.

I don’t have a ton of money to spend $800+ on a integrated ventus/pro missile/tri rig bar so I was looking at switching to a prosvet or svetzero basebar and using arm pad risers instead of headset spacers since I still need some stack. To do this would I need to change to a longer stem to account for the headtube angle? Any benefit to flipping the stem instead of spacers?

Aero-wise I think spacers or flipping the stem is minimal if not irrelevant.

Looks-wise a flipped uprising stem can be poo-pooed by bike snobs

Cost wise if you already have the stem, flip it around and see how it feels.
