I don't want to play "Devils Advocate" Here But Here Goes.
I been using Tubeless for a Long Time
I started on my Merida Kalahari in the Days that you could not even Get Sealant or TR 26er Tyres.
We used to call it Ghetto Tubelass the Ou Manne will Know What I'm Talking about.
I have the Knowledge to Make my Own Sealant as well.
5 years ago I converted my Trusty Merida Big 9 back to Tubes with tube Protectures from Sportsman's Warehouse and Slime Tube Sealant. Initially the bike did feel Heavier I have to admit to that. Eventually I Got rid of the Sealant for Obvious Reasons. Initially I did have a cut in the tube which was resolved by sanding the Rough edges of the tube protectures and Installing Brand New Kenda Tubes. 4 1/2 Years On and 7000 Km with no Punctures.
I recently converted my Trusty Merida 120 back to Tubes and Sportsman's Tube Protectures, Kenda Tubes Brand New from Cycle Lab , no sealant. 6 months on no Punctures. Makes You think.
I have found thorns and nails embedded in the tyre
The Bike once again felt a bit heavier, And IT IS about 100 Grams per wheel.
I have found Thorns and Nails Embedded in the Tyre but no Punctures so far.
Glass has no Chance.
