I have 100m on reel and a fair bit of pole hose (25ft running through pole, but i have a pole tap strapped to pole, so then have enough pole hose after tap that the microbore doesn't move while on one side of the house)
Think that makes sense....lol
Edit : just thought after reading the other posts that ive used 2x100m reels connected up with no pressure change so you'll be fine!
