Tier 4 upgrades are both really good and I use both often. Personally, I find Heavy Duty Suction to be completely useless because I often use MOAB Maulers, which can pop lead. Besides, if a 1/3 Bloonchipper has to deal with a massive rush of bloons it can ignore the leads and focus on bloons that actually pose a threat.
