You have advantage of dealing extra damage and surviving longer if you upgrade Shrikes to Level 11 than using 75 of Level 10 Shrikes. However, I can't say for sure upgrading Shrike is the best since larger warp gate may have better advantage in combat efficiency. Overall, I think upgrading your Tech Lab may be better since you can continue to research other level 11 units since you have extra Scarbide Ingots. But that's my opinion.
