I like the linthog.
I just need to drive over to Poway and get mine replaced...mine was still the old one I guess, that collapses with high flow high heat.
What I did with mine when I first got it, was- I took a small drill bit (about the size of the screen mesh holes) and drilled the bottom of the screen prolly 200 holes in it. I think it has better airflow this way..
I used to use the piglets with it but dont really use them anymore. I vacuum a lot so whatever gets left behind the screen will have to catch it.
Piglets get clogged up too quick- even with good prevac. Sometimes I changed them out 2-3 times on a job..
My linthog is a 2.5" both ends. Regular vynil cuff style.
