I've also experience them, and considering ang ginamit kong reso ko dati is yung stock reso ng lazer. ok sya if you know how to tune it properly. It was in 2000 when i first got these skins, and as far as i can remember, wala pa ata gumagamit nito sa Pinas, or hindi pa masyadong popular. Wala pa double-ply ang Lazer nun.
