Hybrid Shimano?

Left - Aernos Body with Alivio spool; Right - Alivio body with Aernos spool

This trick have been done by a lot of anglers, buy a Shimano 2500 sized reel and buy a spare spool of C3000. Easily convert their reel to a C3000 for the extra line capacity with a 2500 spare spool.

For me, the Aernos XT C3000 have seen very little action as my initial intention is to pair it with my noodle rod, however due to it's heavier body, I have stuck with the Alivio 2500 for a long long time. But recently, after I top up  the spool with some freshly bought Fireline Fused 4lb burst whenever I try to set hook. Losing the fish is bad enough but the time spend to tie the leader and all is killing me. Later found out that I am not the only one, there seems to be one faulty batch for the 4lbs Fireline only, other poundage is okay.

So got my hand on a 300yds of Spiderwire EZ Braid 10lbs, the attraction is that the line feel so thin (like fireline 6lbs maybe) but is at 10lbs rating. Thus decided to spool the entire length of the line into the reel, no joining knots and all. However, I have been adviced that my Alivio 2500 might not be able to take the entire length of the braided line, C3000 might be just nice or have a little excess. Hmm...... give it a quick thought, and decided to swap spool of these 2 reels I have.

Now it is an Alivio body (Modified with extra bearings and ball bearing roller) with an Aernos C3000 spool.  And the Aernos body is now kitted with Alivio 2500 spool. Glad that I am hit with this brainwave, todaks and queenies, here I come........ and there's no escape this time round!

Words of Caution (A few in fact)
Do try out on the same generation of reels, I have just got a cheapo newer generation Shimano reel, yet to try out, but the overall length of the spool is shorter on the new spool
If one spool have bearing support and another dun have, of course it will not be plug and play that easy.
There is a difference in the spool for cheapo and more expensive reels, Die Cast vs Cold Forged.
Finally, you might need to play around with the washers on the shaft if the newly fitted spool does not lay the line evenly at top and bottom.
