I have a Bosch ART 23 Combitrim which uses nylon line 1.6 mm dia.
There is also the option of a more robust 2.25 mm line, but this
comes in precut fixed lengths, with a central metal crimp, and
fits in a different spool, to be used double-ended.

In terms of line wear, the thicker line is, unsurprisingly, much
better, but the price of the precut lengths is prohibitive.

It would clearly be possible to buy a length of thicker line and
wind it onto the standard spool. I can see that auto feed would
probably not work, but when does it?

About the only practical downside that I can see is that the
thicker line would produce greater unbalance forces when in use.

Has anyone else beefed up their strimmer line, or got thoughts on
why it might not be a good idea?

Are you sure your electric strimmer can handle thicker/heavier line? Those
Bosch strimmers have not got good reviews for build quality and I've seen
reviews where the heads fly off.

I normally buy line in large reels, about 100+ metres at a time. Have always
bought it from a specialist shop but see it's also on here...

Just mended my Husqvarna strimmer when the primer bulb sprung a leak, but
then it is over 15 years old and gets very hard use down on our allotment
site keeping the green roadways clear.
