Hedge Fund Pivot

I have 4 yoe on a LO AM with a big book. Performance looks bad and set to continue this way for some time so I’m considering leaving for a HF. I’ve a few questions for the more knowledgeable folk here:

1. How do you know if you’re good enough? AM is sleepy and rarely has turnover so I have put 0 ideas into our concentrated portfolio. I second guess my ability all the time. Comp seems to be market rate to slightly above. I just don’t know if I’m good enough for a more intense environment.
2. How big is a AM move to a L/S role? I’ve no experience on the short side but it seems to be the only roles hiring. Unsure how meaningfully different the role would be.
3. My choice to leave primarily comes from a change in manager - for someone I don’t really respect and style of investing I disagree with. That’s the push - what should the key pull reasons be - presumably head PM, lp concentration , recent track record - am I missing any?

Thanks to all who contribute !
